Hello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it. The grass is very thin and I was told that is because oak trees turn the soil acidic. I had lime put down last year but the grass still looks the same.ello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it.

Slightly Acidic-Tolerant Plants. There are many plants that will tolerate and thrive in slightly acidic soil, including fir, pine, spruce and magnolia trees. Shrubs that do well in acidic soil include blueberries, hydrangeas and dogwood, and perennials that thrive in acidic soil include butterfly weed and most varieties of ferns.
